Rainbow Storage

This is the storage component of Rainbow 🌈, an implementation of Amazon S3 for local development.

Getting Started

$ docker pull atenderholt/rainbow-storage
$ docker network create rainbow
$ docker run --rm --name rainbow-storage --network rainbow -p 9000:9000 -v $PWD/data:/data -v /var/run/docker.sock:/var/run/docker.sock atenderholt/rainbow-storage:1.0.0

Notes:

• Since rainbow-storage is using Docker to start another container (i.e. minio), it needs the following:
  • --name rainbow-storage to correctly bind-mount the data directory from the host into the other container
  • --network rainbow to reference other containers by name
  • -v /var/run/docker.sock:/var/run/docker.sock to control Docker from inside the running container
• Buckets, objects, etc. are persisted to /data.

Questions

• What's Rainbow?

A future project for local implementation of Amazon AWS services.

• Why not LocalStack?

LocalStack appears to be still using the moto implementation of Amazon S3, which doesn't seem to work well with large files. Perhaps this was solved w/ the paid version, but I wanted something lighter weight and not so tightly-coupled to the rest of the LocalStack services (e.g. specify a different targets of Event Notifications).

• Why not just minio?

Minio seems great, but doesn't seem like supports Event Notifications to a local implementation of an Amazon Lambda Functions. It's also not clear how much can be configured with Terraform.
